    摘要: A method of forming a capacitor includes forming a conductive first capacitor electrode material comprising TiN over a substrate. TiN of the TiN-comprising material is oxidized effective to form conductive TiOxNy having resistivity no greater than 1 ohm·cm over the TiN-comprising material where x is greater than 0 and y is from 0 to 1.4. A capacitor dielectric is formed over the conductive TiOxNy. Conductive second capacitor electrode material is formed over the capacitor dielectric. Other aspects and implementations are contemplated, including capacitors independent of method of fabrication.

    摘要: The invention includes a method of depositing a noble metal. A substrate is provided. The substrate has a first region and a second region. The first and second regions are exposed to a mixture comprising a precursor of a noble metal and an oxidant. During the exposure, a layer containing the noble metal is selectively deposited onto the first region relative to the second region. In particular applications, the first region can comprise borophosphosilicate glass, and the second region can comprise either aluminum oxide or doped non-oxidized silicon. The invention also includes capacitor constructions and methods of forming capacitor constructions.

    摘要: The invention includes constructions having two dielectric layers over a conductively-doped semiconductive material. One of the dielectric layers contains aluminum oxide, and the other contains a metal oxide other than aluminum oxide (such metal oxide can be, for example, one or more of hafnium oxide, tantalum oxide, titanium oxide and zirconium oxide). The layer containing aluminum oxide is between the layer containing metal oxide and the conductively-doped semiconductive material. The invention includes capacitor devices having one electrode containing conductively-doped silicon and another electrode containing one or more metals and/or metal compounds. At least two dielectric layers are formed between the two capacitor electrodes, with one of the dielectric layers containing aluminum oxide and the other containing a metal oxide other than aluminum oxide. The invention also includes methods of forming capacitor constructions.

    摘要: A method of forming a capacitor includes forming a conductive metal first electrode layer over a substrate, with the conductive metal being oxidizable to a higher degree at and above an oxidation temperature as compared to any degree of oxidation below the oxidation temperature. At least one oxygen containing vapor precursor is fed to the conductive metal first electrode layer below the oxidation temperature under conditions effective to form a first portion oxide material of a capacitor dielectric region over the conductive metal first electrode layer. At least one vapor precursor is fed over the first portion at a temperature above the oxidation temperature effective to form a second portion oxide material of the capacitor dielectric region over the first portion. The oxide material of the first portion and the oxide material of the second portion are common in chemical composition. A conductive second electrode layer is formed over the second portion oxide material of the capacitor dielectric region.
